B Cable Suspension Screw
The B Cable Suspension Screw is a specialized fastening device for securing messenger cables to utility poles. It attaches messenger suspension clamps securely in overhead installations. The square-headed design allows for easy wrench grip during installation. Commonly used in telecommunications and power distribution networks, it ensures reliable cable support systems.
The B Cable Suspension Screw’s gimlet thread pattern creates strong anchoring in wooden poles. Its integrated washer head distributes load evenly across the mounting surface. The precision-engineered thread design prevents wood splitting during installation. This versatile component adapts to various pole types and mounting configurations.
Features:
• Heavy-duty forged steel construction with hot-dip galvanized finish
• Pre-assembled square nut for quick field installation
• Self-threading gimlet point reduces installation torque requirements
• Integrated washer head design eliminates need for separate washers
• Universal compatibility with standard messenger cable suspension systems

Frequently Asked Questions (FAQ)
What is a B-Cable Suspension Screw used for?
B-Cable Suspension Screws are used to attach messenger suspension clamps when a through bolt cannot be used due to clearance constraints. They are specifically designed for light-duty mounting of cable hangers and cable suspension clamps.
What are the key specifications of a standard B-Cable Suspension Screw?
It features an integral forged washer head, a 7/8″ x 4-1/2″ gimlet thread with cone point, and includes one 5/8″ assembled square nut. The screw is galvanized according to ASTM A-153 standards and weighs approximately 1.87 lb.
What is the installation requirement for B-Cable Suspension Screws?
A 3/4″ pilot hole is required for proper installation. The screw should be installed with appropriate torque, and the forged washer head ensures proper seating against the mounting surface.
What safety standards does a B-Cable Suspension Screw meet?
The screw is hot-dip galvanized to meet ASTM Specification F2329, ensuring corrosion resistance and durability. For heavy-duty applications, the minimum tensile strength is 13,550 lbf with a recommended torque value of 73 ft lb.
How are B-Cable Suspension Screws different from standard bolts?
These screws feature forged collars instead of welded ones for extra strength. They come with cone points to ease starting, and manufacturers include their mark and tensile load designation on the unthreaded section.
